trigger family functions don't use the ID type

[matthewkaney]

Describe the bug

The trigger functions got left behind in the move from Show to an ID type, which means that they no longer work with string keys, for example:

p "looper" $ qtrigger "looper" $ seqP [(0, 2, s "superpiano" # n "c")]

This fails because p "looper" starts a pattern with the id "looper", but the qtrigger is looking up a pattern with the id ""looper"". We need to update the trigger functions and search the rest of the codebase for any other functions with the same problem (by finding all the Show instances and seeing if they're used as pattern ids).
